ELECTRONIC PRODUCTS Non-Intrinsically Safe Relays Boost Your Sensors Load Handling Ability LOAD-PAK , 5 AMP, AC SPST, N.O. Operation AC or DC models Amplify current handling capability of sensors for controlling high power loads Compact, polysulfone bodies are totally encapsulated Impervious to shock or vibration Solid-state reliability GEMS solid-state switching units perform the functions of electro-mechanical relays, LOAD-PAK , with the added reliability and advantages inherent in solid-state. Compact, totally 10 AMP, AC encapsulated, and impervious to shock or vibration, these units mount anywhere even directly on working machinery. 2-3/4 (69.8 mm) MTNG. CTRS. LOAD-PAKS: integrated, solid-state switches that amplify current handling capabilities 7/32 (5.5 mm) of sensors for controlling high power loads. SPST, N.O. operation, AC and DC models. DIA. 2 HOLES. 1-9/16 SPDT-PAKS: enable one low-current sensor to control two independent loads up to 5 (39.6 mm) amps each. Switching is N.O. for one load and N.C. for the other. 2-3/8 FLIP-PAKS: provide low-current, Start-stop or on-off switching for industrial (60.3 mm) motor, liquid level and other control systems. Units hold operational state up to 6-32 THD. 1/2 second during momentary power loss to cut nuisance shutdowns low voltage protection is inherent. 120 VAC and 240 VAC models handle loads to 5 amps. 1 (25.4 mm) Dimensions Intrinsically Safe LOAD-PAK, 10 Amp, A.C.

Electrical Information DC LOAD-PAK: Switching is by means of B+ closure .the DC LOAD-P7/32 AK must be (5.5 mm) wired to the polarity shown. REVERSING POLARITY WILL DESTROY THIS UNIT. DIA. 2 HOLES. 2-3/8 SPDT-PAK: This unit is designed to operate with a load connected to each of the two (60.3 mm) outputs. These loads must be 10 watts, minimum, for correct SPDT switching. One load used alone must be connected to the N.O. terminal. With this load, which may be less than 10 watts, the unit will operate the same as an SPST unit. SPDT-PAK 2-3/8 (60.3 mm) 6-32 THD. Line Transients: While random line transients will not normally harm LOAD-PAKS, they may pass current to some loads for up to 1/2 cycle duration*. AC LOAD-PAKS and the DC LOAD-PAK include transient protection .the SPDT-PAK does not. If load transients are a problem, the external protective circuit, a properly-sized metal oxide 1-3/8 (34.9 mm) varistor, may be used. * Mechanical holding or latching contacts (contactors) may cause some loads to latch under transient conditions.
