Specifications
Output Specification
No. of Output Channels: 32
Output States: Driven high, driven low or off.
Low Side Driver Output
Resistance:
0.6 Ω at 0.5 A
High Side Driver Output
Voltage:
Vext less 1.5 V at 0.4 A
Maximum Current: 0.5 A for Low Side drivers,
0.4 A for High Side drivers,
8 A module total.
Note: for full load conditions,
adequate cooling is assumed.
Maximum Voltage: +50 V*
Output Protection: Current limited, overvoltage
limited, thermal protection.
Overvoltage limit can be used
to limit back emf generated
from inductive loads such as
relay coils.
Vext: User supplied +5 V to +50 V,
applied to multiple pins of
user connector, relative to
front panel ground.
* For full voltage rating, signal sources must be fully
isolated from mains supply and safety earth.

Input Specification
No. of Input Channels: 32
Logic Threshold: Compares selected input
voltage against two reference
voltages, each of which can be
set from 0.3 V to 50 V with
12.5 mV setting resolution.
Settling Time: 50 µs following a state change
or channel selection.
Typical read back time for all
32 states 1.3 ms.
Channel Selection: Single channel selection or
automated sequential access
to all 32 channels.
Maximum Input Voltage: 100 V*
Input Impedance: 1 MΩ
* For full voltage rating, signal sources must be fully
isolated from mains supply and safety earth.
