SECTION 2 - DESCRIPTION AND OPERATION

INTRODUCTION

This section explains the input and output circuitry, control
logic, power and connections for the Digital Slave Module
(DSM). The DSM is a digital input/output interface to a
Multi-Function Processor (MFP) module or Logic Master Mod-
ule (LMM). The MFP/LMM support up to 20 DSMs. These mod-
ules provide the control functions. The master module
communicates with its slave module on a 12-line slave
expander bus as shown in Figure

. Each slave on the slave

expander bus has a unique address set by the slave address
dipswitch (S1) (see Figure

The DSM has two identical but independent I/O groups. Each
group of eight I/O points (circuits) can operate as inputs or outputs.
All points in the group are the same; all are inputs or all are out-
puts. Each point in the group handles one input or output signal .

INPUTS AND OUTPUTS

Digital field inputs are 24 VDC. This voltage indicates an ener-
gized (ON) field device; a 0 VDC input indicates a de-energized
(OFF) field device. Jumpers on the DSM select the outputs for
non-isolated or isolated two-wire configuration.

explains the jumper connections.

NOTE: Due to the number of pins on the P3 connector, twelve
inputs/outputs are separate while the remaining two pairs share ter-
minals. The positive (common) side of Point 5 and 6 are tied
together in each group and Point 7 and 8 are tied together in each
group (refer to Table

). These points must use the same contact

voltage (24 VDC). They are not isolated from each other.
