Basic documentation for OS-1401 module
1. DESCRIPTION AND PARAMETERS
The OS-1401 expansion module contains 12 semiconductor outputs with a semiconductor
switching element and plus common terminal. The module is equipped with removable screw-
type connector with 5.08 mm pitch. The outputs DO0÷DO3 can switch max. 24 V DC, 2 A per
output (the sum of all 4 output currents must not overtake 4.4 A). The outputs DO4÷DO11 can
switch max. 24 V DC, 0.5 A per output. The outputs are galvanically isolated from the internal
circuits (including power supply and communication) and group of outputs are separated one
from another. The status of each output indicated by LED at the front module panel.
