Maxiflex 4HSC Counter Module Model M1711A 4 Channel Universal High Speed Counter Module. DATASHEET FEATURES • Fits in any MAXIFLEX base I/O slot 4 individually Isolated Counter Channels Accepts 9-30Vdc or 3 to5Vdc Pulse Input Individual Channel Activity Indication LED Removable Terminal Blocks In system automatic module detection The Maxiflex M1711 High-Speed Counter module provides field inputs to four 16-bit counters. Two additional internal counters may be configured for a variety of functions. The counters can operate up to a frequency of 200 KHz. Each input may be configured by links inside the module to either be a 3-5V dc, or a 9-30V dc input. The status of the inputs may be read by the Maxiflex CPU directly, providing up to 4 general purpose Digital Inputs when not used as counters. Each input has a green LED to indicate the input signal status. Isolation is 1500 Vrms between individual inputs, and between inputs and system logic. The module plugs into any I/O slot and has a Scan Code and Module ID, which are used by the CPU to detect the module. The two internal counters provided may be used in conjunction with a built in crystal oscillator to provide a variable time base. The internal configuration of the hardware enables frequency measurement and pulse counting over an accurate time period. The counters may be configured for various operating modes. The modes are as follows: • Mode 0 - Event Counting • Mode 1 – Re-triggerable One-Shot Counter • Mode 2 – Rate Generator • Mode 3 – Square Wave Mode • Mode 4 – Software Triggered Strobe • Mode 5 – Hardware Triggered Strobe • Mode 6 – Frequency Measurement SPECIFICATIONS Input Storage Temperature Electronics conformally coated 100% tested to 1500Vac, 50/60Hz for 1 minute - all outputs to logic Logic Power Consumption Insulation Resistance Input Indication (Green LED) LED on channel Active LED off channel Inactive Auto Identification Codes Input Range Counter Range Scan Code InputTermination Types Screw Terminal Wire Size From Logic Power Supply 60mA from 5Vdc max. 68mA from 12Vdc max 0.9W max overall Mass Screw clamp Plug-in Terminal Blocks and 20 way ribbon header 2 2.0mm maximum For manageable wiring to the module, 0.5 mm2 is recommended with 2mm overall outside diameter Excluding Packaging Including Packaging Ordering Information Model Order Code Environmental Operating Temperature Copyright Omniflex ♦ Subject to change without notice
