Detail LU-S14052 8-ch Digital Input Isolated Module.
LU-S14052 8-ch Digital Input Isolated Module.
Summary:
LU-S14052 offers fully independent isolated 8 digital input channels, supports wet contact. For wet contact, the high level input is +4 ~ +30V, the low level input is 0 ~ +1V. The isolation voltage between each channel is 5000VDC, the input impedance is 3 KΩ/0.5 W. LU-S14052 supports Modbus protocol, uses RS-485 to communicate, has built-in optical coupler, can provide 3000VDC isolation voltage. LU-S14052 also has the functions of surge protection, surge absorption, thunder-proof etc.
