• Main control input: 4–20 mA for process signals.
• Secondary output: relay for switching control.
• CT input: current transformer input for current-based measurements.
• RS-485 connectivity: remote monitoring and configuration via RS-485 using Crimson software.
• Protected dual-line display: two 4-digit lines with IP65 front protection and orange/green backlight.
• Universal inputs: accepts pressure transducers, flow meters, current transducers, RTDs and thermocouples configurable from front panel or software.
• Easy configuration: Crimson® software enables fast setup with checkboxes and numeric entries and batch programming.
• Alarms and indicators: configurable status indicators for alarms, control and temperature.
• AC powered: 100–240 VAC operation for global compatibility.

Applications & benefits
Designed for compact industrial installations requiring dependable PID regulation, flexible I/O and remote data access. The clear display and straightforward programming reduce commissioning time and simplify maintenance.
