1 Sensor, 2 Limits, Digital display, Analog-output
The TR122DA is a temperature relay with 2 independant swit- ching points and with analog output. Applications: Monitoring of temperature with pre-alarm and alarm 1 sensor Pt 100 (RTD) 2- or 3-wire-connection Range -199...+850 °C Resistance 0...850 Ω 2 alarms/relays (co- con- tacts) Digital display, 3 digits Monitoring of sensor (break/ short-circuit) Display of MIN- and MAX- values scalable analog output 0/4...20 mA (TR 122 DA only) Universal supply voltage AC/ DC 24-240 V Plug-in housing for easy mounting and service The following parameters can be programmed: Switching points (alarms) Hysteresis (+ or - = MIN or MAX-function) Relay in closed- or operating current mode automatic reset or electronic reclosing lock switching- and switch-back-delay Analog output EasyLimit for simplyfied setting of alarms Code-lock against manipulation of settings rated supply voltage Us sensor Pt 100 (RTD) connection measuring accuracy measuring current connection of sensor analog output measuring range resolution hysteresis switching delays relay-contact test conditions rated ambient temp. range dimensions (h x w x d) attachment protection housing / terminals weight AC/DC 24-240 V, <3W, <5VA (AC 20-264 V, DC 20,4-297 V) Pt 100 according to EN 60 751/IEC 60 751, Resistance 0...850 Ohm line-resistance max. 3 x 22 Ω / 2 x 10 Ω < 0,3 % of value ± 0,5 K (Ω) ≤ 0,8 mA 2-/3-wire, line-resistance max. 2 x 50 Ω/ 3 x 50 Ω 0/4-20 mA, max. 500 Ω, error <0,3% of fullscale ±200 K 0...999 s type 2 (see "general technical informations") see "general technical informations" -20°C...+55°C design S12: 82 x 42 x 121 [mm] on 35 mm DIN rail according to DIN EN 50 022 or with screws M4 P 30 / IP 20 app. 300 g Pt 100-Temperature Relays Type TR 2011-03-30 TR122DA Part numbers: TR122DA T224126 with analog output TR122D T224127 no analog output Monitoring of under- and over-temperature 2-point-controller, e.g. for heating (the second swit- ching point can be used for monitoring the function and release an alarm at over- or undertemperature) 3-point-controller for heating/keeping temperature Monitoring of resistance 0...850 Ohm Transducer for Resistance
