Transformer Temperature Controller

Emco Electronics offers a Transformer Temperature Controller, type EE-801, used for monitoring and controlling the temperature of transformers. Parameters are user programmable such as number of channels, scanning speed, relay thresholds, relay energising delays, hysteresis, max recording threshold, max recording step, relay grouping, etc. The set mode for programming of parameters is password protected for avoiding unauthorized access. Scan/hold mode of operation allows user to monitor either one particular channel or all the channels. Self-calibration feature allows quick and easy calibration of the unit in the field. 4-20 mA output allows SCADA connectivity or can be used for remote indication. Specifications: number of channels – 4; temperature sensors – RTD (PTD 100); set points – programmable for fan, alarm, and trip; temperature range – 10º to 250°C; resolution – 1°C; accuracy – ±2°C; display – 3-digit, 7-segment LED; display speed – 1 to 60 secs; LED indicators – set, max, hold modes, and relay operations; number of relays – 4 (fan, alarm, trip, fault); relay output – 1 C/O contacts for each relay of rating 5 A @ 240 V AC/24 V DC; input/output terminals – suitable for 2.5 mm sq wire; power requirements – 110 V/230 V AC, 50 Hz, 15 VA or universal type (optional); overall dimensions – 200 (H) x 235 (W) x 100 (D) mm; operating temperature – 0-50°C; insulation – 2 kV between shorted terminals and chassis; and enclosure – MS powder coated with acrylic window.
