Pin 2: Positive battery charge plus relay current.
Min 0.50 mA (No relay).
Pin 3: Relay connection.
Pin 4: Output & relay connection. NPN open
connector. Max 10 mA, 47 V A Molex 7720
4 way connector or similar is recommended.
MEU11 and MEU17 – Typical Usage
The examples in figs 6, 7 and 8 show the module
driving a Shrack 48V relay with power derived
from the mains. Type RP330048 or RP331048
(Changeover contracts). In these configurations the
relay pulls in at 47V and is held at above 24V with
mains voltages down to 200V.
EMU11 and EMU17 – Typical Usage
In this case the circuit in fig 6 can be used with a
10K, 3W resistor in place of the 15K, 2W resistor
shown and a 1.3W zener must be connected
between pins 1 and 2 of the module. The circuit
in fig 7 can be used with two 5K1, 1.5W resistors in
place of the 7K5, 1W resistors shown and a 1.3W
zener must be connected between pins 1 and 2
