IMDSI14 ABB 48 VDC DIGITAL INPUT MODULE

Description:

This section explains the inputs and input circuitry, control
logic, logic power and connections for the IMDSI13, IMDSI14,
and IMDSI22 Digital Input Modules. The DSI module is a digital
input interface to Harmony controller. These controllers
provide the control functions. A controller communicates with
its I/O modules on an I/O expander bus as shown in Figure
1-1. Each I/O module on the I/O expander bus has a unique
address set by address dipswitch S1 (Refer to Input Circuits).
