1.5.6 Replacement unit DC501-CS31-AD

1.5.6.1 Introduction
Fig. 84: 3ADR331189S0015_DC501-CS31-AD
The replacement device DC501-CS31-AD of the AC31 adapter series replaces the existing
device DC501-CS31.
The existing device DC501-CS31 supported the use of so-called extension box modules to
increase I/O functionality. The following modules were supported:
● Module AX501 for analog signals: 3 analog inputs, 1 analog output
● Module DI501 for digital signals: 4 digital inputs
● Module DO501 for relay output: 8 relays
The replacement device DC501-CS31-AD does not support the use of extension box modules.
Instead, the functionality of modules AX501 and DI501 is integrated in the replacement device.
The functionality of module DO501 is not supported.
This document describes only changes that have been integrated in the replacement device
and expansions to the existing device DC501-CS31. Thus,
the existing documentation of device DC501-CS31 remains valid and serves as reference. The
extension box modules are documented in the existing documentation of the I/O-S500 hard-
ware. This description is replaced by this document.
