ABB TTH200-Y0 Temperature Transmitter

TTH200: ABB TTH200 series DIN-rail mount temperature transmitter (Head Mount / DIN rail dual mounting, HART protocol)

Y0: Version / configuration code, stands for without local display, basic model, HART 4-20mA output, DIN rail mounting.

Series positioning: The TTH200 is a 2-wire HART temperature transmitter from ABB. It accepts RTD, TC, mV and resistance signals, and serves as a replacement for the discontinued TTF200.

Key Specifications

Sensor Inputs:

RTD: Pt100, Pt1000, Cu50, etc. Supports 2/3/4-wire connection

TC: B,E,J,K,L,N,R,S,T,U and other thermocouple types

Millivolt mV, resistance signal

Accuracy: RTD typical ±0.05℃; Thermocouple typical ±0.08℃

Mounting: DIN rail mount; also can be installed inside sensor connection head (head mount)

Housing: Plastic housing, IP20 (under DIN rail installation)

Configuration: HART communicator, ABB Device Manager, DTM/FDT software

Suffix code Y0: No local LCD display, basic version without extra hardware options.

Comparison: Y1 = with LCD display

Typical Applications

Industrial temperature measurement for HVAC, chemical, power and pharmaceutical industries. Used for temperature acquisition on pipelines and tanks, connected to DCS or PLC, paired with Pt100, K-type thermocouples.

Model Selection & Replacement

1. Same series: TTH200-Y1 (with display)
2. Legacy model replacement: TTF200 → TTH200
3. Domestic alternative: HART DIN rail temperature transmitters (such as Chongqing Chuanyi, Shangrun HART models)

Common Troubleshooting

1. No output: Verify loop voltage ≥12V, check 2-wire wiring for short circuit and polarity
2. Fixed at 4mA: Sensor open circuit / not connected, mismatched configured sensor type (e.g. Pt100 configured while K thermocouple wired)
3. Temperature drift: Check RTD wiring (4-wire preferred), cold junction compensation setting for thermocouple
4. HART communication failure: 250Ω resistor inserted into loop, avoid high-power interference, verify HART address

Spare Parts & Purchasing Notes

Complete order number is not limited to TTH200-Y0; extra codes for sensor type, explosion protection are required

Explosion-proof versions have separate suffixes; TTH200 has intrinsically safe Ex ia variants, confirm explosion-proof requirement before purchase

HS code reference: 90268000 (Temperature transmitter, industrial measuring instrument)

ABB TTH200 Complete Ordering Selection Table

Order model structure: TTH200 [Explosion-proof code] [Display code] + [Additional options]

Examples: TTH200-Y0 = Non-explosion proof, without LCD; TTH200-S1-Y0 = NEPSI intrinsically safe, without LCD

1. Explosion Protection / Certification Code (1st suffix segment)

2. Display Code

✅ Combination example: TTH200-Y0 (non-explosion proof no display); TTH200-E1-Y1 (ATEX intrinsically safe + LCD)

3. Housing / Mounting Accessory Options (added separately, incompatible with some explosion-proof models)

⚠️ Note: Some explosion-proof models cannot be matched with H1/H2/H3 head housing options. Confirm before order.

4. Functional Additional Options

5. Supported Sensor Input Selection (configured in software, stated in order remarks)

RTD Resistance Temperature Detector

Pt100(IEC60751 0.00385)【Default】、Pt100(JIS)、Pt10、Pt50、Pt200、Pt500、Pt1000；Ni50/Ni100/Ni120/Ni1000；Cu10/Cu100；Resistance signal 0~500Ω / 0~5000Ω; support 2/3/4-wire

Thermocouple TC

K、J、T、E、N、R、S、B、L(DIN43710)、U、C、D；mV signal: -125~125mV / -125~1100mV

Cold junction compensation: Built-in(default) / external cold junction / no compensation (B-type thermocouple recommended no compensation)

7. Complete Ordering Examples
8. TTH200-Y0

Non-explosion proof, no LCD, DIN rail mounting; configured Pt100, range 0~200℃

2. TTH200-S1-Y1+CS

NEPSI intrinsically safe, with LCD, SIL2 declaration; K-type thermocouple, built-in cold junction compensation

3. TTH200-E1-Y0+H2

ATEX intrinsically safe, no LCD, polyester IP65 head housing, head mount Pt100

8. Selection Notes
9. Y0/Y1 are display codes, NOT explosion-proof codes, a common confusion. For TTH200-Y0, Y0=no display; the preceding Y means non-explosion proof.
10. DIN rail installation only needs transmitter body + DIN rail clip kit, no H1/H2 head housing. H-series housings are used for sensor head mounting inside temperature probe junction box.
11. Confirm hazardous area classification (Zone/Div) and temperature class T6 for explosion-proof models; NEPSI S1 version is preferred for domestic hazardous projects.
12. Measurement range, sensor type and TAG are configuration parameters, submit in order remarks for factory pre-configuration; or configure on-site via HART communicator after delivery.
13. Cross Series Replacement Reference

TTH200: Single channel, no sensor drift monitoring (this model)

TTH300: Dual channel, support sensor redundancy and drift monitoring, higher performance

Legacy TTF200: Discontinued, direct replacement by TTH200-Y0/Y1
