INPUTS Actual devices provide AC or DC input signals to the KBMS Series of Programmable Relays These include push buttons limit switches proximity switches pressure switches toggle switches or any other devices that provide an on off signal The models with analog inputs 0 10 VDC use a volt age that represents a value The analog inputs are provided by a transducer or process signal In a typical application these signals can represent temperature fluid levels or distance The analog inputs can also be used as on off inputs OUTPUTS The KBMS provides independent isolated output relay contacts rated for 8 amps 250 VAC NEMA type B300 or 24 VDC These outputs can turn on solenoid valves lamps motor contactors relays and many other devices used in machine and process control INTERNAL PROGRAM The KBMS programmable relay uses an internal ladder logic program composed of individual rungs that perform decision making processes based on inputs outputs counters timers and internal memory relay s When the rung condition is True the output relay counter timer or internal coil is enabled Many of the functions of the KBMS are described in later sections of this manual 14 The KBMS Programmable Relays are easily programmed using the 8 buttons on the unit SEL ESC DEL 9 Select Used to show the selection of available instructions types Holding this button for 3 seconds in the Stop mode will display

Timer The On Delay timer type 1 is used to offset the On state of an event for a preset amount of time This time is the preset value 008 0 in the example which will change the state of the status instruc tion when the timer s accumulated value reaches the preset value The On Delay timer can be value reten 26 tive which accumulates time into the function block by adding the time values for which the logic rung is True The status will change state when the accumulated value is equal or greater to the preset value This timer status instruction is then addressed in the ladder logic of the program Figures 20 and 21 illustrate the On Delay timer operation in addition to the retentive value feature The input I2 is enabled therefore the rung is True The timer starts its clock and when the accu mulated value is equal or greater to the preset value in the timer the status instruc tion in the example T1 changes state If the value is not reached the retentive fea ture of this timer type will hold the accumulated value 005 6 sec and add any sub sequent time events to the accumulated value This will change the status instruc tion state once the accumulated value is equal or greater than the preset value 010 0 The accumulated value of a retentive timer will remain in the timer until the reset instruction or input instruction is True Figure 22 Type 2 On Delay Instruction
