2 relay outputs max. 8A/250V for direct control of contactors (potential-free O/R contacts).

Pulse-width modulation (PWM) outputs for solid-state relays (SSR), each 14V/60mA, adjustable rate (1Hz to 10Hz) and pattern, overload/restart function, error detection/indication.

Handheld controller (or wall-mounted) with high-contrast 4.5” LC display. Simultaneous display of all key process values, color change of the main process value in case of deviations. Intuitive touch interface with capacitive dial (tactile feedback). Up to 99 user-named programs.

Records all relevant process data for at least 48 hours, stored on USB stick in CSV format. Event memory for quick diagnosis of application or technical issues. Program names can be assigned via text file.

Powerful 32-bit ARM microprocessor-based controller. Non-volatile event log for sensor failure, short circuit, power outage, and user errors. Continuous process monitoring. Real-time clock for timestamping log data to ensure secure diagnostics. Self-monitoring of all relevant components. Adaptive P/PI/PID controller with continuous auto-tune. Optional CAN interface for connection to the industrial I/O box.

Number of segments (each segment consists of a ramp followed by a hold time)

Input time/day for automatic program start and stop (e.g., to preheat kilns before a work shift or shut them down for the weekend).

Bluetooth communication

Via WebBox (up to 4/16 controllers) or WebServer; bentrup app for iOS & Android.

Energy-efficient power supply 85-264V AC/DC (optional 24V), maximum power dissipation 8W, configurable power failure bridging, ambient temperature -10°C to 60°C, humidity 10% to 90% non-condensing, highest level of active and passive EMC, tested according to IEC801/4-IV, CE conformity. Compatible with all plug standards (e.g., HAN7D, HAN15D, CPC14) for kiln connections.

Handheld or wall-mounted housing 107 x 200 mm made of high-impact ABS with transparent, anti-glare display cover. Total thickness only 24 mm, weight 470 g (depending on installed options), optional stainless steel wall bracket with bolts.

Configurable for thermocouples (S, R, K, J, N, E, B), standard voltage signals (20mV/50mV/10V), current (0-20mA, 4-20mA) or resistance (0-500Ω, PT100), signal conversion for zirconia probes with Lambda and CO calculation (combustion equation). Auto-zero, internal or external cold junction compensation (CJC), accuracy 0.05%, resolution 17-bit, sampling rate 16Hz, adjustable signal smoothing and error correction.

Relay outputs max. 8A/250V for direct contactor control (potential-free on request).

Pulse-width modulated (PWM) outputs for solid-state relays, each 14V/60mA, adjustable cycle rate (1Hz to 10Hz) & switching patterns, overload/restart, error diagnostics, and display.

Quickly detects heating power consumption and provides timely warnings. Maximum power draw is measured under full load, either through real current/voltage measurement of the PM3 module or via I/O-Box current/voltage scan integrated into the EMC log.

Integrated web browser allows remote access to the TC705 from anywhere for log data, event log, configuration changes, program execution, or sequence control.
