Teleste MPH241 - Configuring Contact Closure Channels; Contact Closure Inputs; Contact Closure Output

40 MPH200 series video encoders WebUI user manual
Upper screw terminal connector
(pins 9...16) on front panel is used
for contact closure connections.
Contact closure loop (CCL) connection
The MPH200 series video encoders provide two inputs and one
contact closure output channel line.
Contact closure inputs
There are two different CC input connection types. First one is for a normal
short circuit which is called “dry contact closure”. Dry contact closure
enables you to switch ON & OFF input signals between connector’s
contact pins (internal power source). Second type is called “Optoisolated”
current loop input signals (logical 0 = 0.0VDC...+1.4VDC and logical 1 =
+2.2VDC...+30.0VDC) between contact pins (external power source).
Input pins nominal current consumption is 3 mA.
Contact closure output
CC output is a normal relay on/off - output signal (30V / 0.6A) between
connector’s contact pins.
Note! If voltage output is needed from output, do not use Vcc
(10mA) pin for it. Instead use external voltage source or device
power supply for it. See an example connection bottom.
