Selection & installation notes
- The catalogue title says RT-K-X, while the actual official selection chart uses RT-ME-X. Order using a confirmed full RT-M code from the chart; no RT-K-X-to-RT-M substitution is assumed.
- The prose gives a 125 V KT limit despite specifying a 1.5KE36CA suppressor, and KD mentions 125 V despite the relay’s 30 VDC resistive rating. Obtain a load-specific approved voltage; do not use either 125 V statement as the module rating.
- 108 mm is board width, not overall width; the current original drawing shows 124 mm. Dimensions are L × W × H with ±1 mm source tolerance.
- RC suppression across NO contacts causes off-state leakage and load voltage. Provide isolation for service and verify compatibility with small electronic loads.
- Confirm load energy, suppression polarity, fuse coordination and common wiring. Input NPN/PNP compatibility does not remove output polarity requirements.
