PCD2.A400
Digital output module, 8 outputs, transistors, 5…32 VDC/0.5 A
Low cost output module with 8 transistor outputs 5 … 500 mA, without short circuit protection. For non-isolated circuits in the voltage range 5 … 32 VDC.
Technical data (for version “B”)*
Number of outputs
Output current
8, electrically connected
5 … 500 mA (leakage current max. 0,1 mA)
Within the voltage range 5 … 24 VDC, the load resistance should be at least 48 Ω
Total current per module
Operating mode
Voltage range
4 A on 100 % duty cycle
Source operation (positive switching)
5 … 32 VDC, smoothed
10 … 25 VDC, pulsed
Voltage drop
Output delay
Resistance to interference acc. to IEC 801-4
≤ 0.4 V at 0.5 A
Switch-on delay typically 10 μs
Switch-off delay typically 50 μs
(ohmic load 5 … 500 mA), longer with inductive load, because of the protective diode.
4 kV under direct coupling
2 kV under capacitive coupling
(whole trunk group)
1 … 25 mA, typically 15 mA Internal current consumption
(from +5 V bus)
Internal current consumption
(from V+ bus)
0 mA
External current consumption Load current
Terminals Type L: Pluggable 10-pole screw terminal block
(4 405 4847 0), for wires up to 1.5 mm²
* Version “B” available since February 1995
(Version “A” was fitted with bipolar transistors. These had a shorter recovery time, but also a higher residual voltage, resulting in a restriction on 100 % loading)

Fuse: It is recommended that each module should be separately protected with a fast-blow (S) 4 A fuse.
Watchdog: This module can be used on all base addresses; there is no interaction with the watchdog on the CPUs. For details, please refer to the “Watchdog” section of the manual 26-856_ENG, which describes the correct use of the watchdog in conjunction with PCD2 components.
I/O modules and I/O terminal blocks may only be plugged in and removed when the Saia PCD® and the external +24 V are disconnected from the power supply.
