Coil Suppressor Modules

These modules clip onto the right hand side of the control relay and the electrical connection is instantly made. Adding an input module is still possible.
RC Circuits (Resistor-Capacitor)
● Effective protection for circuits highly sensitive to “high frequency” interference. ● Voltage limited to 3 Uc maximum and oscillating frequency limited to 400 Hz maximum. ● Slight increase in drop-out time (1.2 to 2 times the normal time).
For Mounting On:	Operational Voltage					Catalog Number		$ Price
CAD (Vac)	24 to 48 Vac					LAD4RCE		26.20
	110 to 240 Vac					LAD4RCU		26.20
Varistors (Peak Limiting)
● Protection provided by limiting the transient voltage value to 2 Uc maximum. ● Maximum reduction of transient voltage peaks. ● Slight increase in drop-out time (1.1 to 1.5 times the normal time).
CAD (Vac)	24 to 48 Vac					LAD4VE		26.20
	50 to 127 Vac					LAD4VG		26.20
	110 to 250 Vac					LAD4VU		26.20
Bidirectional Peak Limiting Diode
● Protection provided by limiting the transient voltage value to 2 Uc maximum. ● Maximum reduction of transient voltage peaks.
CAD (Vac)	24 Vac					LAD4TB		26.20
	72 Vac					LAD4TS		26.20
