West 1/16 DIN High/Low Limit Control, Universal Input, Latching Output
Shipment 3 Weeks typical
The ISE/West 6700+provides a programmable safety cut out with optional outputs for annunciators and alarms. A latched relay cuts power to the process if it exceeds the safe value. The unit must be reset before the process can continue. Plug in direct replacement for the N6700 / N6701 series. We fully configure the control prior to shipment so that it is truly plug & play. Configurations can be easily modified if your requirements change. | |

Features | |
Output Configuration - Up to 3 Total. 1 latching trip relay, max 2 alarms relays, max 2 DC linear retransmit (PV or limit value). Alarm 1 & 2 Types - Process high, process low, setpoint deviation, band, logical OR alarms or trip annunciator. Limit Action - Latching relay output when PV exceeds set value. Selectable for high or low trip activation. Output Reset Action - Limit output can be reset only when exceed condition is absent. Local or remote reset options. Annunciator Reset Action - Annunciator output can be reset at any time. Local or remote reset options. Human Interface - 4 button operation, dual 4 digit 10mm & 8mm high LED displays. Exceed, output & alarm indicators. Red Upper display / Green Lower Display Standard. Red Upper/Lower Optional. PC Configuration - Configuration via PC only. Dedicated config socket (comms option not required | |
Input | |
Thermocouple - J, K, R, S, T, B, L, C, Pt-Rh20% vs Pt-Rh40% & N. RTD - 3 Wire PT100, 50ohm per lead maximum (balanced). DC Linear - 0-20/4- 20mA, 0-50/10-50mV, 0-5/1-5/0-10/2-10V. Scaleable -1999 to 9999, decimal point selectable. Impedance - >10Mohm for Thermocouple and mV ranges, 47Kohm for V ranges and 5ohm for mA ranges. Accuracy - +/- 0.1% of input span +/- 1 LSD (T/C CJC better than 1C). Sampling - 4 per second, 14 bit resolution approximately. Sensor Break Detection - <2 secs (except zero based DC ranges), control O/P's turn off, high alarms activate for T/C and mV ranges, low alarms activate for RTD, mA or V ranges. | |
