Safety: NRTL listed to UL61010-1 and CAN/CSA C22.2 NO. 61010-1-12; UL 61010-2-030 and CAN/CSA-22.2 NO.61010-2-030-12. Conforms with European Union Low Voltage Directive
EMC: Conforms to European Union EMC Directive
The 3762 switches voltages up to 1000 V peak or currents up to 0.5 A. The current carry capacity of each relay contact is 1 A. Two-pole relays switch both circuit HI and circuit LO for full floating measurements. A Guard input common to all channels is provided for shielding or as a guard driven by a single instrument. Guards may be isolated by removing resistors installed at each input. Multiple switched guard circuits can be achieved by removing the jumper and connecting circuit Guard to the LO input terminal. The 3760 does not connect to the 6 common buses on the 3706A backplane. Daisy chaining cards can be achieved by using an output channel.
