Product Overview Recap

Single-phase solid-state contactor (contactless SSR)

コントロール: 24 ワシントンDCで; 主回路: ≤600 V AC, 評価された 30 あ; DIN rail mounted; optoelectronic isolation; bidirectional triac output; optimized for frequent switching of single-phase AC loads

主な利点: Arc-free, 機械的摩耗がない, 低騒音, high-speed frequent switching. 制限: Self-heating, current derating mandatory for inductive loads.

Critical Premise: Only supports single-phase AC loads; cannot directly drive three-phase motors

1. General Standard Industrial Scenarios

1.1 Resistive Heating Loads (最も一般的なアプリケーション)

1. Control of heating tubes in ovens, tunnel furnaces and thermal processing equipment
2. Heating circuits for injection molding and extruder barrels
3. Industrial thermostats, hot air blowers and duct electric heaters
4. Heating elements of heat-sealing machines and hot stamping equipment in packaging machines

✅ Advantage: PID high-frequency continuous switching by temperature controllers rapidly wears contacts of mechanical contactors; ELR1 perfectly fits this working condition

1.2 Single-Phase Fans & パンプス (誘導負荷)

Application requirement: 25%~30% current derating for load selection

1. Control cabinet cooling fans, industrial exhaust fans and ducted single-phase fans
2. Small single-phase centrifugal pumps, circulating water pumps and fume exhaust fans
3. Air supply units for drying equipment

⚠️ Note: Large inrush current upon motor startup; recommended actual load ≤20~22 A for the 30 モデル

1.3 Lighting Loads

1. High-power halogen lamp banks and infrared heating lamp arrays in workshops
2. High-power lighting arrays in test laboratories

❌ Not recommended: LED drivers and electronic ballast loads (high inrush current; RC snubber circuit is recommended)

2. Industry-Specific Field Applications

▶ Packaging Machinery

1. Heating control for heat shrink tunnels
2. Actuation of heat-seal bars on vertical / horizontal packaging machines
3. Single-phase drive motors on conveying lines and hot air drying systems

▶ Plastics & Rubber Machinery

1. Heating rod control for each temperature zone of extruders and pelletizers
2. Start-stop control of heating circuits for mold temperature controllers

▶ HVAC & Environmental Test Equipment

1. Heaters for high-low temperature test chambers and constant temperature & humidity chambers
2. Hot air circulation systems for purification equipment
3. Heating modules of industrial dehumidifiers

▶ New Energy & Lithium Battery Production Lines

1. Heating control for electrode drying ovens
2. Hot air devices for dust removal equipment

アドバンテージ: No sparks for dust-free workshops (the device itself is NOT explosion-proof; explosion-proof enclosure is mandatory for hazardous areas)

▶ Food & 製薬機器

1. Electric heating systems for food baking lines and sterilization equipment
2. Hot air drying units for cleaning equipment

アドバンテージ: Contactless operation prevents metallic dust generation, meeting operation requirements for cleanrooms

▶ Automated Test Equipment

1. Switching of high-power loads on aging test benches
2. Adjustable AC load switching devices in laboratories
3. Cluster control of high-power AC solenoid coils
4. 適用できないシナリオ (Selection Red Lines)
5. ❌ Direct control of three-phase asynchronous motors (ELR1 is single-phase SSR; only controls one phase. Strictly prohibited as main three-phase switch. Select ELR3 series for three-phase loads)
6. ❌ Frequent startup of high-power single-phase compressors (severe startup inrush current may cause triac breakdown)
7. ❌ Applications relying on the device for long-term overload & 短絡保護 (solid-state relays have poor short-circuit withstand capability; サーキットブレーカー / fuses must be installed upstream)
8. ❌ Unprotected outdoor open-air installation (must be fitted inside control cabinets)
9. ❌ High-frequency high-voltage inductive loads without RC snubber circuits
10. Recommended Supporting Configuration for On-Site Deployment
11. 誘導負荷 (モーター, コイル): Parallel Phoenix Contact RC absorption modules to suppress back EMF
12. Multiple units mounted side-by-side on DIN rail: Maintain minimum clearance ≥10 mm between adjacent devices; current derating required when cabinet ambient temperature＞45 ℃
13. Upstream protection: Deploy gG fuses; circuit breakers alone cannot provide reliable short-circuit protection
14. Preferred component for PID temperature control systems; switching frequency can reach several cycles per second, service life far exceeding mechanical contactors

Mounting Specification — Phoenix Contact ELR 1-24DC/600AC-30 (2297154)

1. Standard Mounting Form

標準取付: Snap-on installation on 35 mm DINレール (TH35-7.5)

1. Integrated DIN rail locking clip on device rear side; no additional brackets required
2. Mandatory mounting orientation: 縦置き設置 (terminals facing up/down; cooling fins arranged vertically)

❌ Horizontal side mounting & inverted installation are forbidden! Horizontal placement blocks natural convection cooling, leading to overheating shutdown and triac damage.

2. 取り付け & Dismantling Procedures
3. Hook the upper clip onto the DIN rail;
4. Press down the main body until an audible “クリック” confirms the lower clip locks onto the rail;
5. 除去: Pry open the bottom clip with a flat screwdriver and lift the device upwards.
6. Thermal Clearance Requirements (致命的! 30 A solid-state contactors generate considerable heat)

Single Independent Installation

Vertical clearance (トップ & 底): ≥50 mm ventilation space

Lateral clearance: ≥10 mm if adjacent space is vacant

Multiple Units Mounted Side-by-Side on the Same DIN Rail

Minimum clearance between adjacent devices: ≥10 mm

Zero-clearance tight arrangement is prohibited

Maintain ≥15 mm clearance if cabinet temperature＞40 ℃

For large-scale continuous installation, forced air cooling via cabinet axial fans is recommended

4. 配線仕様 (ネジ端子)

Terminal Assignment

A1(+), A2(-): 24 V DC control circuit

L, 外: Main circuit for single-phase AC loads

Wiring Parameters

1. 端子の種類: Anti-loosening screw terminals
2. Applicable conductors:

単芯線: 0.5～10 mm²

Stranded flexible wire: Crimp lugs are recommended

3. Recommended tightening torque: 1.2～1.5 N·m

⚠️ Insufficient torque → excessive heating; excessive torque → thread slipping or terminal base cracking.

Wiring Layout Suggestion

Separate routing for control cables (A1/A2) and high-power cables (L/OUT) 電磁干渉を減らすために

Minimize length of power wiring to reduce voltage drop and heat generation

5. Ambient Operating Boundary Conditions
6. 設置場所: Inside control cabinets, IP20保護等級

❌ Direct exposure to open air; avoid dust, moisture and condensation contacting the device

2. Permissible operating temperature: -20 ℃ ～ +60 ℃

Current derating is mandatory when ambient temperature＞40 ℃

3. Avoid these installation positions:

Directly above transformers, power resistors and other heat-generating components

Poorly ventilated dead zones inside cabinets

Locations with persistent strong vibration (continuous vibration loosens terminal screws)

6. Optional Heat Dissipation Accessories

For continuous full-load operation in enclosed cabinets, DIN rail-mounted aluminum heat sinks can be attached to the rear of the device to reduce housing temperature.

No heat sink supplied as standard; cooling relies on integrated housing fins for natural convection.

7. Strictly Prohibited Operations
8. Do not suspend the device by cables; all mechanical load shall be supported by the DIN rail
9. Do not block cooling fins on sides and rear surface
10. Do not connect multiple ELR1 units in parallel for current sharing (inconsistent on-resistance causes uneven current distribution and burnout)
11. Do not install contactors / circuit breakers tightly adjacent to solid-state contactors without heat clearance

Standard Description for Engineering Drawings

The ELR1-24DC/600AC-30 shall be vertically mounted on TH35 standard DIN rail. Lateral clearance between adjacent devices ≥10 mm. Separate routing for control and power circuits. 端子締め付けトルク: 1.2~1.5 N·m. Ensure adequate natural ventilation for heat dissipation.
