Elmo manual Terminals for ISP mounted in 3U size ENC, Gnd

5.3Terminals for ISP mounted in 3U size ENC.

The MBA-ISP/3UE is designed for Elmo enclosures. It has screw type terminals for the power and D-type connectors for the signals.

The Potential Free Inhibit Input is applicable only when the "inverted inhibit logic" is used (R18 in the amplifier is inserted). An opto-Coupler (IL5) is used to isolate between the Inhibit signal and the amplifier circuit. Activating this opto-coupler is done by inserting R1 on the mother board according to the following relation:

R1 = 100 x Vinh (ohm)

Vinh - voltage in the inhibit input.

Standard value is 2.4K (For 24 volts) Source must be capable of source or sink 10mA.
