AB | 1746-IH16 | Current Sinking DC Input Module

The PLC 1746-IH16 is a general-purpose input module. The 1746-IH16 uses a voltage category of 90-146V DC sink. It has a maximum ON and OFF signal delay of 9ms. The 1746-IH16 input module’s maximum off-state current is 0.8mA and it draws a backplane current of 85mA at 5V and of 0A at 24V. It can be used on general purpose 125V DC inputs.

The 1746-IH16's maximum off-state voltage is 20V DC and its nominal input current is 2.01mA at 125V or 2.25mA at 132V DC. When the 1746-IH16 module is connected in parallel with an inductive load, a surge suppression mechanism should be applied across the load to protect the 1746-IH16 input module from the resulting damage of a reverse voltage situation.
The 1746-IH16 has a power dissipation rating of 0.32 watts per point, a minimum dissipation of 0.217 watts, and a total dissipation of 5.17 watts. The 1746-IH16 is not for home usage. It must be fitted into enclosures which adhere to the proper environmental conditions to reduce injury to personnel and/or other systems.
