Honeywell Analog Input Hi level (16ch)900A16-0101
Relay Output Module (900H01-xxxx)
The Relay Output Module provides eight individual
galvanically isolated, electromechanical relay outputs.
Four of the outputs are Form-C, and the other four are
Form-A. Outputs are not fused in the Relay module.
Install a fuse for each output at the field device that is
appropriate for the load and the wire used.
There is a green LED state indicator for each channel on
the module to indicate when a digital output is ON.
A green blinking status LED on the module indicates
when the module is being scanned. An amber blinking
status LED indicates when channels are forced and a red
status LED when module diagnostics exist.

Digital Output Module – DC Type (900H02-xxxx)
The DC Digital Output module provides 16 outputs
separated in to 2 groups of 8 channels each that are
powered externally. Each group has a pair of screw
terminals for +V and COM connections. The outputs are
low side switching (current sinking) type. Overload
protection is built into each output; when tripped the
power must be recycled to reset the module.
There is a green LED state indicator for each channel on
the module to indicate when a digital output is ON.
A green blinking status LED on the module indicates
when the module is being scanned. An amber blinking
status LED indicates when channels are forced and a red
status LED when module diagnostics exist..
