Integrated Multi-Function EZ-ZONE RM Programmable Application Blocks Compare • Greater than, less than, equal, not equal, greater than or equal, less than or equal Counters • Counts up or down, loads predetermined value on the load signal. Output is active when the count value equals or exceeds predetermined target value Linearization • Interpolated or stepped relationship Logic • And, nand, or, nor, equal, not equal, latch, flip flop Math • Average, process scale, deviation scale, differential (subtraction), ratio (divide), add, multiply, absolute difference, min., max., square root, sample and hold, altitude and dew point Process Value • Sensor backup, average, crossover, wet/dry bulb, switch over, differential (subtraction), ratio (divide), add, multiply, absolute difference, min., max., square root, altitude, visala and dew point Special Output Function • Compressor - turns on-off compressor for one or two loops (cool and dehumidify with single compressor) • Motorized valve - turns on-off motor open/closed outputs causing valve to represent desired power level • Sequencer - turns on-off up to four outputs to distribute a single power across all outputs with linear and progressive load wearing Timers • On pulse - produces an output of fixed time on the active edge of timer run signal • Delay - output is a delayed start of timer run and off at same time • One shot - oven timer • Retentive - measures timer run signal and output on when accumulated time exceeds target Variable • User value for digital or analog variable EZ-ZONE RM Family Comparison Control Module High-Density Control Module High-Density Limit Module Expansion Module High-Density Scanner Number of modules per system 1 to 16 1 to 16 1 to 16 1 to 16 1 to 16 Number of PID loops per module 1 to 4 4, 8, 12 or 16 0 0 0 Number of limit loops per module 1 to 4 0 4, 8 or 12 0 0 Number of monitoring points per module 1 to 3 0 0 0 4, 8, 12 or 16 Mechanical relays per module 1 to 8 4 or 8 4, 6 or 8 4, 8 or 12 4 or 8 Digital I/O points per module 6 6 or 12 6 or 7 6, 12, 18 or 24 6 or 12 Actions (events) per module 8 24 16 8 16 Alarms per module 8 24 16 8 16 Compare per module 4 24 16 8 24 Counters per module 4 24 16 8 24 Linearization per module 4 24 16 8 24 Logic per module 4 24 16 8 24 Math per module 8 24 16 8 24 Process value per module 1 to 4 1 to 24 0 0 16 Special output function per module 4 0 0 4 0 Timers per module 4 24 16 8 24 Variable per module 8 24 16 8 24 WATLOW® 215
