The one-slot
OSP-B114 (order no. 1505.4711.02) has 2 D-Sub I/O con-
nectors, interlock LED, solid-state SPDT relay (SSR, K14) with 3 female SMA connec-
tors and electromechanical DPDT power relay (K11) with 4 female N connectors.

The module is designed for the following tasks in small or medium systems for electro-
magnetic susceptibility (EMS) measurements:
●
IN
The male D-Sub 9 connector labeled "IN" provides 4 input channels and 5 other
lines, as shown in
–
The 4 digital input channels (input lines at pins 4, 5, 8 and 9) have no influence
on the module's internal interface logic. Instead, you can read out the state of
these universal IN channels to your external computer. You can use these IN
channels, for example, for controlling your application by the state of various
door contacts or light grids.
These 4 input channels are specified for up to 5
V (TTL). If you use a higher
voltage level up to +28
V
DC (as provided by pin
6, for example), do not
over-
load
the input: for voltages >
5

DC up to 28

Chapter 2.1.11, "Connecting Control Cables"
The input channels can be read at any time. Each channel is protected by a
lowpass filter and two TVS diodes against transient disturbances.
–
Pin 1 is a ground contact.
–
Use the "Interlock Loop" line on pin
2 together with pin
6 ("+28
V
DC") to con-
nect the interlock door contact. Hence, pin
2 provides the basic door-state
information to the module's interlock logic.
