TCM - TRIAC CONVERTER MODULE Accepts unloaded, high off-state leakage triac output from sensors and programmable controllers. LCM - LOGIC CONVERTER MODULE Interfaces with CMOS, TTL, and other logic circuits up to +28 VDC, at speeds to 50 KHz. Allows Cub Counters to share sensor outputs with other series counters. These miniature sized modules are completely encapsulated in PVC, which provides protection against oil, water, dirt, and mechanical damage. They can be quickly and easily mounted to most surfaces by using the self-stick adhesive pad. VCM - VOLTAGE CONVERTER MODULES SPECIFICATIONS These modules provide a convenient way to adapt RLC Counters to most any 1. INPUT: VCM1 = 4 to 50 VAC/DC, 50/60 Hz machine control voltage signal. They also make it easy to upgrade electro- VCM2 = 50 to 270 VAC/DC, 50/60 Hz mechanical counter installations with RLC Counters. 2. OUTPUT: Solid state DC contact closure VCMs are available in two input voltage ranges that cover the spectrum Output rating: 30 VDC at 100 mA max from 4-270 V. The non-polarized input of these modules will accept A.C. (50/60 Output Isolation: 2300 V RMS Hz) or D.C. voltages at input cycles up to 30 Hz. The output uses MOSFET Off State Leakage: 1 A max technology that is compatible with either the L.S. Count or Remote Reset inputs 3. FREQUENCY: Max output frequency 20 Hz of RLC Counters. Electrical isolation between input and output is achieved by 4. ENVIRONMENT: 0-50 C means of an internal opto-isolator rated at 2300 VRMS.

It is specifically designed to 1. INPUT: 115 VAC 10% (50/60 Hz) 10 mA max current draw operate with photo-electric sensors and programmable controllers that have 115 2. FREQUENCY: 10 Hz max output VAC Triac outputs. Due to protective suppression circuits connected in parallel 3. OUTPUT: Solid state DC contact closure with Triacs, these outputs have a high OFF-State Leakage current, which, if Output rating: 30 VDC at 100 mA unloaded, is sufficient to keep a VCM in the ON condition continuously. Output Isolation: 2300 V RMS The TCM incorporates a current bias that offsets output leakage currents Off State Leakage: 1 A max up to 4 mA and allows the application of RLC Counters to most unloaded 4. ENVIRONMENT: 0-50 C 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: VCMs 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.

The output is inverted with respect to the 5. ENVIRONMENT: 0-50 C input which causes the CUB Counter to increment on the leading (positive going) edge of a count pulse.
