Mounting Kits
Four mounting kits are offered for the Model 545/546 module.
Each mounting kit consists of a PC card, adjustment pots,
and a 15-pin mating connector. Two of the mounting kits also
have low-profile relays mounted on the PC card. Mounting
kits can be ordered with the Model 545/546 module installed
or can be ordered separately. The price of the mounting kits
includes the pots, relays, and connector. The combined price
is computed by adding the price of the module to the price of
the mounting kit.
The mounting kits all accept one Model 545/546 module.
Trimming potentiometers are included for setting the high and
low trip points. Gain of the input amplifier may be changed by
jumpering on the mounting kit, or by adding a fixed resistor.
Also, hysteresis can be increased by adding impedance
across terminals provided on the mounting kits. The four
mounting kits provide a choice of output configuration. The
differences and features of each mounting kit are shown
below.
Relays
The relays used are a low-profile SPST type. Contact rating
is 1A at 26 VDC or 0.5A at 115 VAC with a resistive load. For
inductive loads derate by 50%. Coil impedance is 310 ohms
±10%. response time is 10 milliseconds. Height is 0.415".
Model 015 Connector
A 15-pin mating connector with edge guides is supplied with
each mounting kit. A diagram of the connector is shown in
Figure 16.

Model MK376
The three outputs are connected for current-sinking operation.
This model has provision for external remote adjustment of
set-points and external latch/unlatching operation .
Model MK377
The three outputs are connected for current-sourcing
operation. This is the emitter-follower configuration. As with
the MK376, the set-points can be set remotely or on the
mounting kit. Latching and unlatching control is also bought
out on the connector.
