Specification:
Specification:
Measuring range: -199,9 ... +650,0 °C (standard) -199,9 ... +999,9 °F (please specify when ordering) Resolution: 0,1 °C Accuracy: ± 0,03 % FS ± 1 digit (at nominal temperature = 25°C) Measuring rate: approx 3 measurements / sec. Linearisation: parameter memorized digitally Sensor: not included (please order separately) see page 94 Pt 100, 4-wire (any probe or cable length possible wihout recalibration). Probes fully interchangeable (any Pt 100 sensors in 2 or 3-wire design existing at customers can also be connected, as GIR1002Pt100 is equipped with a digital zero-offset adjustment) Self-diagnosis: permanent self-diagnosis of device to ensure troublefree operation by means of integrated precision reference resistor.
Measuring range: -1999 ... +9999 digit, first and last value freely adjustable Resolution: any decimal point possible Measuring rate: approx 3 measurements / sec. (at .../FAST: 40 meas. / sec.) Accuracy (at nominal temperature): ± 0.1% FS ± 1 digit (at .../FAST: ± 0,5 % FS ± 1 digit) Standard signal input: (freely selectable) 0 to 20 mA (Ri=50 Ohm) 0 to 1 V (Ri=30 kOhm) 4 to 20 mA (Ri=50 Ohm) 0 to 10 V (Ri=300 kOhm) 2-, 3- or 4-wire. Other input values or extra high Ri upon request. Power supply for sensor: integrated isolated power supply for measuring transducer: 18 V DC ±5 %, 20 mA. Tare function: (upon request). Please specify when ordering. Self-diagnosis: permanent self-diagnosis to ensure trouble-free operation.
Filter: software filter to suppress interference signal. Delay in display approx. 1.5 s. If necessary, filter can be switched off. Min./Max. value memory: both the highest and lowest value recorded during operation can be called up by pressing a button. Fault indication: probe damage, probe short-circuit, values no longer within measuring range. Interface: compatible to RS 485 (up to 16 devices linkable via one 2-wire interface). Connection to RS 232 by means of optional GRS485. Analog output [optional]: 4-20mA, 0-20mA or 0-10V, scale to be selected individually, electrically isolated. Controller configuration: (freely selectable - 9 different types available): Type 0: display Type 3: same as type 2, alarm has to be cleared manually Type 6: same as type 5, alarm has to be cleared Type 1: 3-level controller Type 4: 2-level controller with pre-selectable hysteresis manually Type 2: 2-level controller with min./max. Type 5: same as type 4, in addition min./max. alarm, auto- Type 7: 2-level controller alarm self-clearing matically following set-point value, alarm self-clearing Type 8: 3-level controller with pre-selectable hysteresis Type 9: special type, to customers specifications - no adjustments OPTION: additional Min/Max alarm relay: max. 42VDC/AC, 0.5A Setting of set-point value: via front side keyboard (lockable upon request) Control range: can be limited by manufacturer upon request Setting of alarm: via front side keyboard or automatically following Alarm delay: 0 to 99 min., pre-programmed by manufacturer (if you want to set yourself, please specify, too) Hysteresis: digital setting of any value (depending on switch on / switch off values set). Minimum hysteresis: 0.1 °C resp. 1 digit. Relay: 2 volt-free relays , 1 changeover contact and 1 normally-open contact, switching output: 10 A (ohmic load) 250 V 50/60 Hz. (optional 2 changeover contact available). Please specify preferred relay fault position (eg sensor not working): open (standard) or closed. The second relay is principally energised (eg for type 2); in case of alarm (i.e. values above/below min./max. value set) the contact will be broken. Semiconductor relay: (optionally - against upcharge - please order separately) if desired, one or two relays can be taken out to allow control of one or two external semiconductor relays (eg. 50A). Control voltage 12 V DC for external semiconductor relay will then be provided. (refer to options) Display: 4 digit red LED, 13 mm high Front: membrane keyboard IP65. Add. sealing for panel-mounting (option) Housing: standard rack type housing 48 x 96 x 100 mm (H x W x D) Panel cutout: 43 x 90.5 mm (H x W) Clamping terminals: screw-type/plug-in terminals Working temperature: 0 to 50°C (permissible ambient temperature for operation of GIR1002...). If temperatures fall below 0°C, device may however be used for permanent operation (please contact us). Power supply: standard 230 V AC 50/60 Hz, approx. 3 VA, for other voltages please refer to options.
