5. 選択 & 交換ガイドライン

5.1 Core Selection Criteria

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

✅ I/O Requirement:

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

出力: Verify 2 安全性 + 2 auxiliary contacts meet control demands.

接点容量: Ensure load current ≤2.5A (AC-15/DC-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 アップグレード & 交換オプション

Option A: Same Series Function Upgrade

More channels: 2981800 → 2981810 (2 チャンネル, 4 safety contacts)

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

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

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

代替機種: 2981900 (PSRmini-SCP-24DC/ESD/4X1/30)

アドバンテージ: Only 17.5mm width (5mm narrower), 同一の機能, キャビネットのスペースを節約します.

Option C: Migrate from PSRclassic to PSRmodular (システム拡張)

解決: PSRmodular system + safety function modules

アドバンテージ: Multi-channel expandable; integrates safety gate, 非常停止, light curtain and other safety functions, suitable for complex safety systems.
