Tracker 332+

The Tracker 322 PID controller with a universal input, 10/24VDC-sensor / loop excitation supply output and a serial RS485 interface. Available as 110/230VAC powered or 24VDC / AC powered modules. This module requires a Tracker 340 logic expansion module and/or an analogue output option fitted for PID Control. We quote our base price if no model is selected.

• Fully featured PID controllers with auto-tune for heat and heat/cool applications
• Ideal for integrated multi-loop applications where single loop integrity is important
• Separate gains for linear, water or air cooling with reverse or direct acting control
• Universal input for Thermocouples, RTD sensors, 20mA, and other process signals
• Current limited 10 / 24VDC Sensor / Loop excitation supply outputs
• Thermocouple ageing alarm predicts near future failure
• Adjustable PWM cycle times, output slew rates and output power limits
• Adjustable setpoint ramp rates and sensor break fall back controller power (%)
• Partial load failure alarm for electrical heater faults
• Process alarms can be configured to have a High, Low or Deviation (Band) Action
• Separate on and off hysterisis and on and off delay timers to stop fleeting alarms
• Alarm blocking to stop nuisance alarms on plant start up
• Latching alarms - reset by a logic input on T340 expansion module or the serial interface
• Modbus RTU compatible isolated RS485 interface for configuration and real time data
• Modbus floating point and a simple ASCII based protocols available with auto detection
• Up to 128 devices on a single RS485 network without the need for repeaters
• Communications loss alarm (requires a Tracker 340 logic module Relay or TTL output)
• Block read / write features for fast data transfer
• Standard Mini-B 5-pin USB configuration, the only connection needed for configuration
• Simultaneous use of Serial Interface and USB ports
• Free Configuration software
• 5 Year warranty

Tracker 340 Logic Expansion Module

• Offers a maximum of 4 extra relays with volt free change over contacts and 2 logic inputs
• Allows an extra 4 process alarms/system alarms or can be used as a PWM control outputs
• Logic inputs can be configured for external control of functions (e.g. latched alarm reset)
• Powered and controlled by the T332 module (mounted to the right of the T332)
• Optional TTL outputs (replaces relays)

Analogue Output Option

• High resolution (16 bit) output for 0-20mA, 4-20mA and 0-10VDC signals
• Can be used as a PID control output (Heat or Cool)
• Scaling to any part of the measurement range including reverse scaling (e.g. 20-4mA)
• Sink or source modes for mA signals
• Independent output damping filter for noisy signals
• Can transmit maximum, minimum or average values, or values set via the serial interface.
