M1250 MINI•PLS Specifications

Input Power:
    105--135 VAC, 50/60 Hz, 35 W exclusive of load
    (220 VAC or 240 VAC option)

Operating Temperature:
–    10 to +130 °F (–23 to +55 °C)

Resolution and Scale Factor:
    Resolution and scale factor are defined as follows:
    The Resolution is defined to be equal to the counts per
    revolution of the resolver.The Scale Factor is defined as
    the desired resolution (counts/rev) minus one.
    Resolution: 17 to 1000
    Scale Factor: 16 to 999

Scan Time:
    57 μsec for 1 cam module
    64 μsec for 2 cam modules
    71 μsec for 3 cam modules
    78 μsec for 4 cam modules
    85 μsec for 5 cam modules

Number of Dual Setpoints Per Channel (On/Off):
     Resolution ÷ 2

Offset:
    Programmable “0” to full revolution

Motion Detector Limits:
    Low setpoint: up to 1899 RPM (max.)
    High setpoint: up to 1900 RPM (max.)

Number of programmable channels:
    40 ( 5 output modules with 8 channels each)

Slave Systems:
    Up to 7 M1250’s may be slaved to one master unit, giving     additional 7 x 40 channels (total 320) using the same
    position transducer (The slave shares the position
    transducer with the master.)

Input/Output

Program Enable:
    Contact closure to Sig. Ref; or a solid-state switch 0.8 V
     @ 10 mA.

Motion Detector Output:
    NPN sinking, 30 VDC max. @ 100 mA (for Output
    Specifications for N, P, T, see Table 4 on the next page.)

Remote Power Relay Outputs:
    For Cam and Motion outputs requiring higher current
    ratings, a separate Remote Power Relay chassis
    Autotech's part number, ASY-RLYCH-xxxx, can be used.
    The relay chassis is connected to an N type of cam
    module using a prewired cable.
    Relay Chassis Input Power : 120 VAC 50/60 Hz.
    Number of outputs: 8 or 16 cam outputs plus one
         motion output.
    Cam Module required: N type.
    Cable: Prewired 4 feet with DB15 connector on one end.
    Relays: Relay chassis is available for EM or Solid-state
        relays. Electromechanical relays (Part# KSD-A12DC-10A):
        120 VAC @ 10 Amp, SPST

        Solid-State AC relay (Part# KSS-120AC-3AMP)
        24–280 VAC @ 0.2–3 Amp, zero cross-over
        switching triac output relay,optically isolated
        Solid-State DC relays:
            Part# KSS-60VDC-3AMP: 960 VDC @ 3
            Amp, optically isolated Special Output Modules
            Part# KSS-200VDC-1Amp :0–200 VDC @ 1
            Amp, optically isolated Special Output Modules

        characteristics same as those of logic level cam
        output modules. See Table 1.
    Module Update Rate:
        Background task, RPM dependent (consult factory).
        PC Synch Circuit and Data Transfer Command:
        (Optional)
                0 to 24 Volt logic input (edge triggered, i.e., data
                transfer on both rising and falling edges)
                Logic Low: 0 to 0.8 V @ 3.2 mA
                Logic High: >2.4 V @ 0.4 mA
                Timings: Data latches between 30 ms–100 ms after
                data transfer edge
