West P6700 1/16 Din Limit Alarm Unit
TECHNICAL DATA
| Features | |
| Output Configuration | Up to 3 possible, for latching trip relays, alarm/annuncator relays, 24VDC transmitter power supply or retransmit of process value or limit trip setpoint |
| Alarm 1 & 2 Types | Process high, process low, Limit SP deviation, band, logical OR alarms or trip annunciator. Alarms have fully adjustable hysteresis. |
| 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, optional choice of colours (Red/Red, Red/Green, Green/Red or Green/Green), plus 4 LED indicators |
| PC Configuration | Off-line configuration from PC serial port to dedicated config socket (comms option not required). Configuration Software for Windows 98 or higher. West Part Number: PS1-CON |
| Input | |
| Thermocouple | J, K, C, R, S, T, B, L, N & PtRh20%vsPtRh40%. |
| RTD | 3 Wire PT100, 50 Ohm per lead maximum (balanced) |
| DC Linear | 0 to 20mA, 4 to 20mA, 0 to 50mV, 10 to 50mV, 0 to 5V, 1 to 5V, 0 to 10V, 2 to 10V. Scaleable -1999 to 9999, with adjustable decimal point |
| Impedance | >10M Ohm for Thermocouple and mV ranges, 47K Ohm for V ranges and 5 Ohm for mA ranges |
| Accuracy | ±0.1% of input range ±1 LSD (T/C CJC better than 1°C) |
| Sampling | 4 per second, 14 bit resolution approximately |
| Sensor Break Detection | < 2 secs (except zero based DC ranges), Limit trip and annunciators activate. High alarms activate for Temperature and mV ranges, low alarms activate for, mA or V ranges |
| Output and Options | |
| Limit Trip Relay Outputs | Latching SPDT, contacts 5Amp resistive at 240V AC, >100,000 operations |
| Alarm Relay Outputs | Non-latching SPDT, contacts 2Amp resistive at 240V AC, >500,000 operations |
| SSR Driver Alarm Outputs | Drive capability >10V DC in 500 Ohm minimum |
| Triac Alarm Outputs | 0.01 to 1 Amp AC, 20 to 280Vrms, 47 to 63Hz |
| DC Linear Retransmit Outputs | 0 to 20mA, 4 to 20mA into 500 Ohm max, 0 to 10V, 2 to 10V, 0 to 5V into 500 Ohm min. Accuracy ±0.25% at 250 Ohm (degrades linearly to 0.5% for increasing burden to specified limits) |
| Transmitter Power Supply | Output 24VDC (nominal) into 910 Ohm minimum to power external devices |
| Communications | 2 Wire RS485, 1200 to 19200 Baud, Modbus and ASCII protocol (selectable) |

OVERVIEW
The West 6700+ is a programmable safety cut out with optional outputs for annunciators and alarms. A latched relay cuts power to your process if safe values are exceeded. The unit must be reset before the process can continue. It has the improved Plus Series hardware and user interface for optimal ease of use.
