5.1 Core Selection Criteria

✅ Safety Level Matching: Ensure required safety rating (SIL/PL/Cat.) does not exceed product capability (ซิล 3 / Cat.4 PL e).

✅ I/O Requirement:

ป้อนข้อมูล: 1 channel sufficient; confirm NC or NO contact type.

เอาท์พุต: Verify 2 ความปลอดภัย + 2 auxiliary contacts meet control demands.

ความจุการติดต่อ: Ensure load current ≤2.5A (เอซี-15/ดีซี-13).

✅ Delay Requirement: Confirm 0.1–30s adjustable range covers equipment stopping time.

✅ Reset Mode: Select auto or manual reset according to operation needs.

✅ Environmental Adaptation: Operating temperature ≤60℃ and humidity within industrial standard range.

5.2 อัพเกรด & ตัวเลือกการทดแทน

Option A: Same Series Function Upgrade

More channels: 2981800 → 2981810 (2 ช่อง, 4 safety contacts)

Add alarm output: 2981800 → 2981820 (with alarm output)

Shorter delay: 2981800 → 2981801 (0.1–10s) หรือ 2981802 (0.1–1s)

Option B: Migrate from PSRclassic to PSRmini (Space Optimization)

รุ่นทดแทน: 2981900 (PSRmini-SCP-24DC/ESD/4X1/30)

ข้อได้เปรียบ: Only 17.5mm width (5mm narrower), ฟังก์ชั่นที่เหมือนกัน, saves cabinet space.

Option C: Migrate from PSRclassic to PSRmodular (System Expansion)

สารละลาย: PSRmodular system + safety function modules

ข้อได้เปรียบ: Multi-channel expandable; integrates safety gate, E-stop, light curtain and other safety functions, suitable for complex safety systems.

5.3 การแก้ไขปัญหาทั่วไป

ติดต่อฟีนิกซ์ 2981800 (PSR-SCP-24DC/ESD/4X1/30) is a single-channel safety relay with adjustable power-off delay, specially designed for emergency stop and safety gate monitoring, reaching the highest safety level SIL 3 / Cat.4 PL e.
