Figure 42: D9412GV4/D7412GV4 v2.00 (and higher) Input Points and Peripheral Devices
(D125B, D129, D130) System Wiring
1 - (Optional): For 24 V applications use a UL 1481
listed, regulated, power-limited 24 VDC power
supply with a D130 Relay Module. Refer to the
D130 Installation Instructions (P/N: F01U072455)
for correct wiring requirements.
2 - D130 Relay Module
