DIN RAIL PULSE/FREQUENCY/CONDITIONER SEM1600F DUAL OR SINGLE UNIVERSAL FREQUENCY INPUT(S) PLUS EXCITATION MODES FREQUENCY (0.01 to 65000) Hz COUNTER (DC to 1000) Hz RATE/TOTALISE, K FACTOR, M FACTOR, MATHS FUNCTIONS SECOND INPUT ACTS AS RE-SET IN SINGLE CHANNEL MODE VOLT FREE CONTACT TRIP,LATCHED TRIP,PULSE ACTIONS OUTPUT(S) ISOLATED OUTPUT CURRENT SINK/SOURCE or BIPOLAR VOLTAGE AC/DC POWER SUPPLY INTRODUCTION The product is a cost effective smart powered conditioner that accepts all common process pulse signals with a frequency range between (0.01 to 65000) Hz in standard configuration and (DC to 1000) Hz in counter mode. Typical applications would be to measure flow or batch counting. The product has a built in capability to operate as a dual input which allows differential flow / count measurement with advanced maths functions. Or, as a single channel input, with an external reset contact. When operated in signal channel mode, the discrete input can be programmed to reset the total counter, batch counter or latched relay. The input can also be programmed to control the total counter direction with a combination of count up /count down or halt modes available. A volt free output contact is provided capable of operating as either a trip, latched trip or pulsed trip. High and low level trip functions are also available. The output stage offers either voltage, bipolar voltage or active / passive current re-transmission signals. The retransmission signal can be ranged to a scale anywhere within the process range. The product uses a USB port for configuration, together with a simple to use free menu driven software configuration tool, allowing the user to take advantage of the products comprehensive specification. The device can be configured to operate in three modes:- Frequency to process signal mode plus trip Advanced frequency mode with K factor, M factor, totalise, rate, maths functions, process signal + trip Counter mode with K factor, totalise, maths functions, process signal + trip SUPPLY + 1 (10 to 48) Vdc PSU (10 to 32) Vac - 2 UNIVERSAL FREQUENCY OUTPUT INPUT 3 Externally Internal Excitation OUTPUT powered powered 9 Load Voltage Current Current 6 6 + Voltage V Channel A 7 Output 5 5 - - Channel B Load Vout Or 8 Discrete + 4 INPUT Common 10 11 CONTACT OUTPUT 12 USB Page 1 of 7 DIN RAIL PULSE/FREQUENCY/CONDITIONER OUTPUT VOLT FREE CONTACT PC CONFIGURATION Max Voltage 24 V dc Current 0.5 A dc EQUIPMENT Trip Actions High/Low level trip, COMPUTER Running Windows XP or later with High/Low latched trip USB port Frequency Mode Signal Rate A, Total A, Rate B, Total B, USB CABLE A to mini B Rate Maths Function, Total Maths Function.
