DWYER INSTRUMENTS, INC. | dwyer-inst.com356 Relays/ Current Switches/Transformers PROCESS CONTROLThe Series 783 & 784 Ice Cube Relays are full-featured relays that can be used to handle loads up to 15 amps for AC or DC circuits. It features a flag status indicator and a LED status lamp to let the user know when the relay is activated. In order to differentiate between AC and DC actuated models, the push-to-test button is color coded and a removable lock-down lever holds the test button in place.FEATURES/BENEFITS• Clear plastic housing to easily view the contacts• Flag and LED status indicators for visual confirmation of relay state• Socket mounted for quick installation/replacementAPPLICATIONS• Refrigeration compressor systems• HVAC motor controls• Water/wastewater pump controlFEATURES/BENEFITS • Integral mounting flange for quick installation • Solid core or split core configurations APPLICATIONS • BAS • HVAC SPECIFICATIONSOperating and Load Voltage Range: 24-240 VAC; 24 VDC.Electrical Connection: Silver alloy plug-in contacts.Switching Operation: 3PDT or 4PDT.Electrical Rating: 15 A @ 120 VAC 50/60 Hz; 12 A @ 277 VAC 50/60 Hz or 28 VDC.Temperature Limits: Storage: -40 to 185°F (-40 to 85°C); Operation: -40 to 131°F (-40 to 55°C).Power Consumption: 783: 1.5 VA; 1.4 W; 784: 1.5 VA; 1.5 W.Cycle Life: 100,000 cycles (electrical); 10,000,000 cycles (mechanical).Housing: Plastic polycarbonate.Weight: 783: 2.1 oz (60 g); 784: 2.8 oz (80 g).Agency Approvals: CE, CSA, cULus, cURus.ICE CUBE RELAYS3PDT or 4PDT Operation1-3/32[27.90]3/16[4.75]1/64[0.51]17/64[6.57]1-37/64[40.00]1-7/32[30.80]3/16[4.75]1-17/32[39.10]1-19/32[40.60]1-3/32[27.90]17/64[6.60]1/64[0.50]Pictures shown with socket accessory (sold separately)7837841-27/32 [47.0] 2-35/64 [64.5] 63/64 [24.9] 1-5/64 [27.4] 1-9/16 [39.6] 1-5/64 [27.4] 2-35/64 [64.5] 2-9/16 [65.0] 2-45/64 [68.6] 2-9/16 [65.0] 2-45/64 [68.6] 2-9/16 [65.0] 1-1/16 [26.9] 1-1/16 [26.9] CURRENT SWITCHES Optional Relay Output, Solid or Split Core Case The Series SCS Current Switches are ideal for monitoring whether fans, pumps, or motors are operating. The current flowing through the core of the device powers the circuit without an external power supply. All models have a built in solid state output and are easy to install. Optional LED’s and 10 Amp relay modules are available. The Series SCS is available in both split and solid core configurations. SPECIFICATIONS Output: Isolated, 1 A @ 30 VAC/DC max, NO. External Relay: SPST N.O., 10 A at 260 VAC (5 A at 30 VDC). Power Requirements: None, self-powered. Temperature Limits: 5 to 140°F (-15 to 60°C). Isolation Voltage: 600 VAC RMS. Frequency: 50/60 Hz. Enclosure Rating: UL, 94 V-0 flammability rated, ABS plastic housing. Agency Approvals: CE, cULus.
