M1450 and M1451 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 (See Table 1)
     Resolution and scale factor are defined as follows:
     The Resolution is defined to be equal to the counts
    per turn of the resolver. The Scale Factor is defined
    as the desired resolution (counts/rev) minus one.

Offset:
    Programmable “0” to full revolution;

Rate Offset: (See Table 1)
    Programmable, “0” to full revolution (CAUTION: entering
    too much rate offset may result in more than one
    revolution offset for higher speeds.) Rate offset resolution: Programmable in tenths of scale factor units per ten RPM.

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 M1450s 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.)

Decimal Point on Display
In Model M1450-400, a decimal point may be placed arbitrarily
after any digit. This decimal point is just for the convenience of
display, and does not affect the data. Decimal point is not available in M1450-300 and M1450-MROF.

Input/Output

Program Enable:
Contact closure to customer power supply common (–Vs); or a
solid-state switch 0.8 V @ 10 mA

ModZ Input:
Contact closure to customer power supply +VS; or 10 to 28 V
logic input, Logic false: 4 VDC@1mAandLogic true: 10VDC@
10 mA to 28 VDC @ 30 mA
Number of Mod Z channels: (See Table 1)

Motion Detector Output:
NPN sinking, 30 VDC max. @ 100 mA

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 or NI type
    Cable: Prewired with DB15 connector on both ends.

    Relays: Chassis is available for EM or Solid-state relays.
        Electromagnetic relays (Part# KSD-A12DC-10A):
            120 VAC @ 10 Amp, SPST
        Solid-State AC Relay (KSS-120AC-3AMP):
            24–280VAC @ 0.2–3 Amp, zero cross-over
            switching triac output relay,optically isolated

    Solid-State DC Relays
        KSS-60VDC-3AMP:
            9–60 VDC @ 3 Amp, optically isolated
        KSS-200VDC-1Amp:
            0–200VDC @ 1 Amp, optically isolated


Special Output Modules

        characteristics same as those of logic level cam
        output modules. (See Table 2)
    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 μs – 100 μs after data
