Isolated Transmitters: 600T Series 631T 632T 633T Multi-Channel 4-Wire Isolators
■Models
▲631T: Single I/O channel
▲632T: Dual I/O channel
▲633T: Single input, dual output (splitter)
■These units receive 4-20mA process current inputs and provide isolated 4-20mA output signals. Each channel operates independently and is isolated from the others to prevent interaction between channels. Galvanic isolation eliminates ground loops, reduces noise, and blocks transient signals
■Units are shipped with factory calibration for quick installation. These isolators also automatically compensate for load resistance variations, so re-calibration is rarely necessary. However, adjustable zero and span trim pots are provided to ensure precise calibration for maintenance requirements and long term serviceability.
■These isolators generate a 24V input excitation supply suitable for powering one or two 2-wire transmitters. The supply is current limited at each output to prevent any excitation short from pulling down the internal power supply. The internal DC supply improves system performance by isolating loops on a single or dual channel basis. It saves space, complexity, and the expense of installing additional supplies to power your field loops.
■Input / Output Ranges
▲4 to 20mA DC input
▲4 to 20mA DC output
■Power Requirement
▲12-36V DC
▲90-250V AC (125V DC ±10%)
▲Four-wire isolated transmitter
■Approvals
▲CE marked. UL, cUL listed.
▲Class I, Division 2, Groups A, B, C, D
●Key Features & Benefits
■Two channels in a single unit saves space and reduces costs.
■Signal splitter model (633T) provides two iden-tical isolated outputs from one input signal.
■Built-in isolated excitation supply with short circuit protection can drive up to two field 2-wire process loops
■Full isolation safely separates each input channel, each output channel, the excitation supply, and power.
■Excellent accuracy and stability ensure reliable operation in hostile environments.
■Low input burden keeps voltage drop to less than 1.5V for full-scale current.
■Supports wide 0 to 1000 ohm load range and no trimming is required if the load varies.
■Current limiting safely limits output to 27mA.
■Pluggable terminals, zero/span trim pots and power LEDs make installation, maintenance, and long term service easy
