SPECIFICATIONS

1. Each UDC-24 system controller shall be capable of driving up to 24 individual phase controllable SSR's with an input control requirement not exceeding 20mA each. One DB25 output connector shall contain all 24 PMW outputs. An optional interface PCB and wall mount enclosure shall permit the use of CAT5E wiring and remote signal distribution up to 1000'. Termination via punch-down or RJ-45 shall be optional.

2. Control input protocol shall be standard USITT DMX-512A and/or 0-10 Volt DC analog. A total of 24 separate/isolated analog inputs shall be provided. UDC-24's output shall be highest takes precedence (HTP) of the input control signals. The DMX input shall be fully opto-isolated for controller protection up to 2500 Volts. The UDC-24 shall contain RMD compliant hardware.

3. The UDC-24 system controller shall contain a backlit LCD display and five (5) buttons to allow simple user interface for programming and system testing.

4. Each UDC-24 system controller shall have dual switching power supplies capable of 85-265VAC at 50 or 60 Hz.

5. All connections shall be via premium "breakaway" style connectors. It shall not be necessary to re-wire any portion of the control electronics to facilitate system repair or replacement.

6. It shall be possible to program the following system functions without any proprietary programmers, software or a PC:

Dimmer Test to verify the PWM output of any or all output signals.
DMX Address Select in single channel increments.
DMX Source Location either the front or rear of the controller.
DMX Termination to select end-of-line if applicable.
DMX Hold Time of the last received DMX levels on loss of signal.
Phase Patch of any dimmer (PWM output) to any referenced power phase.
Dimmer Curve Selection of either square, linear, direct translation or non-dim PWM output.
Voltage Regulation enable/disable to compensate for fluctuations in line voltage.
Voltage Limit of each dimmer from 0.5 to 127.5VAC in 0.5 VAC increments.
Analog Block to enable/disable all analog system inputs.
Voltage Output Adjust of the external power supply (9.5 to 13.2VDC).
Analog Patch of any input to any PWM output (24 x 24).
Analog Filter to enable additional input filtering where excessive noise exists.
Grand Master to enable/disable the GM control over the 24 primary analog inputs.
Bump Control to enable/disable the front panel bump/test buttons for security.
OC Output Driver to select the trigger source (DMX or analog) of the auxiliary contact.
Defaults to permit fast selection of all factory default programming/settings.
Printout of any/all programmed parameters via the infrared LED transmitter.
LCD View Angle Adjust to compensate for extreme viewing angles.

7. It shall be possible to view the following system functions on the system LCD via simple and intuitive menuing without any proprietary programmers, software or a PC:

DMX Test to permit fast testing of the DMX signal integrity.
Analog Test of each analog input individually. Displays analog input level in percent.
Line Voltage Test to check the voltage of each incoming phase.
Line Frequency to check the incoming line frequency.
Temperature will display the internal operating temperature of the micro-controller.
Serial # will display the silICON serial number for the UDC-24 controller.
Version will display the current software version of the UDC-24 controller.

8. A keypad lockout feature shall permit electronic lock/unlock of the controller keypad.

9. The systems controller shall contain status L.E.D. indicators of correct line voltage, phase reference voltage, DMX receive, output level, and system over-temp.

10. Control electronics shall contain the necessary hardware for future implementation of both RDM (ESTA Remote Device Management) and JDM (Johnson Device Management).
