TCM - TRIAC CONVERTER MODULE

The TCM is a specialized version of the VCM. It is specifically designed to

operate with photo-electric sensors and programmable controllers that have 115
VAC Triac outputs. Due to protective suppression circuits connected in parallel
with Triacs, these outputs have a high OFF-State Leakage current, which, if
unloaded, is sufficient to keep a VCM in the ON condition continuously.

The TCM incorporates a current bias that offsets output leakage currents

up to 4 mA and allows the application of RLC Counters to most unloaded
Triac outputs. These modules are available for operation with 115 VAC ±10%
50/60 Hz only. They operate at count rates up to 10 cps, and also provide
input/output electrical isolation. Connections for the TCM are the same as
those for the VCM.

Note: VCM’s can be used with Triac outputs that are also driving substantial

loads, since the load will shunt the leakage current away from the VCM input.

LCM - CONVERTER MODULE

The LCM adapts CUB* Counters to practically any type of logic and sensor

output, and to any count signal voltage from +3 to +28 VDC. The module
accepts input count pulses from NPN Open-Collector Transistor outputs,
Bi-Polar outputs, or sourcing outputs such as Emitter-Follower or PNP Open-
Collector Transistors (Sourcing outputs must be externally loaded with a load of
10 Kohms or less)
. The LCM output is a Bi-Polar drive that is compatible with
either the Low-Speed or High-Speed Counter inputs as well as the Remote
Reset input** of the CUB Counters. The output is inverted with respect to the
input which causes the CUB Counter to increment on the leading (positive
going)
edge of a count pulse. Power for operation of the LCM can be normally
obtained from the existing D.C. power supply used to operate the sensor or other
logic circuitry. When count pulse signals are generated by switch contacts the
LCM output can be applied to the L.S. input of the CUB to de-bounce these
pulses. Minimum pulse width when driving the L.S. input is 10 msec and
maximum count rate is 50 cps.

* LCM intended for use with CUB1,2,3,and 7.
** When used to operate Remote Reset input, the LCM will reset counter when

input to LCM goes high due to signal inversion.
