DESCRIPTION Symbols on equipment: Each I/O channel of the DT333-0700 is modeled after an ANSI/ISA Type IV transmitter. Isolated input channels interface with thermocouple sensors (type J, K, T, R, S, B, E or N) or ±100mV/±1V signal sources and modulate isolated DC outputs that may drive current or voltage. -

Page 6: Electrical Connections
Use adequate wire insulation and follow proper wiring practice, as common mode voltages can exist on signal wiring. As a rule, output wires are normally separated from input wiring for safety, as well as for low noise pickup. Acromag, Inc. Tel: 248-295-0880 - 6 - - 6 - https://www.acromag.com... -
Page 7: Sensor Input Connections
The positive input is on the left and labeled “+”, and the negative input is to its right. See connection figure below per input model. Each output channel may drive current or voltage from separate channel terminals that share a return. Acromag, Inc. Tel: 248-295-0880 - 7 - - 7 - https://www.acromag.com... -
