Expansion module IR-1501
The IR-1501 expansion module is designed for scanning of up to 4 binary signals 24 V DC / AC with
common pole (according to connection minus, plus or alternating power supply), type 1. The module has
8 relay outputs with a make contact and common pole. The module is fitted with a fixed terminal board
(for terminal parameters refer to Table 1.1.1). The inputs DI0÷DI3 allow to realize special functions
identical with the inputs of the CP-1004 basic module (detailed information on the functions and
connection examples are described in chapter 1.1.2. The relay outputs can close max. 230 V AC, 3 A (the
current through the common pole is max. 10 A). The inputs are galvanically isolated from the internal
circuits (power supply and communication to the basic module) and the inputs are isolated from the
outputs, the status of each input is indicated on the front panel of the module.

Basic connection diagram of the IR-1501 module
Notes for connection:
1.
The inputs DI0 ÷ DI3 allow to realize special functions (connection of incremental scanners,
counters, etc.), detailed information can be found in chapter 1.1.2.
2.
The relay outputs are isolated from the other circuits by a 4kV isolation.
