Functions
The RNF22R2MMW supports a wide range of functions, each detailed with timing diagrams illustrating input and output behavior. These functions include various types of delays, flashing relays, and specialized relays.
Function A: Power on-delay
Description: When power is applied to A1-A2, the output R1/R2 activates after a delay period (T). The timing period (T) is adjustable.
Function At: Power on-delay with pause / summation control
Description: Similar to Function A, but includes pause and summation control capabilities for the timing period.
Function Ac: On-delay & Off-delay with control signal
Description: This function combines on-delay and off-delay behavior controlled by an external signal on Y1.
Function Ad: Pulse delayed relay with control signal
Description: A pulse is generated with a delay upon receiving a control signal.
Function Ah: Pulse delayed relay (single cycle) with control signal
Description: A single-cycle pulse is delayed upon receiving a control signal.
Function Ak: Asymmetrical on-delay & off-delay with control signal
Description: Asymmetrical on-delay and off-delay behavior controlled by an external signal.
Function B: Interval Relay (Single Shot) With Control Signal
Description: A single-shot interval relay activated by a control signal.
Function Bw: Double Interval Relay With Control Signal
Description: A double interval relay activated by a control signal.
Function C: Off-delay relay with control signal
Description: The output deactivates after a delay when the control signal is removed.
Function D: Symmetrical flashing relay (starting pulse off)
Description: Provides symmetrical flashing output where the OFF state starts first.
Function Dt: Symmetrical flashing relay (starting pulse off) & with pause / summation control
Description: Symmetrical flashing with pause and summation control.
Function Di: Symmetrical flashing relay (starting pulse on)
Description: Provides symmetrical flashing output where the ON state starts first.
Function Dit: Symmetrical flashing relay (starting pulse on) & with pause / summation control
Description: Symmetrical flashing with pause and summation control, starting with the ON state.
Function H: Interval relay
Description: A basic interval relay function.
Function Ht: Interval relay & with pause / summation control
Description: Interval relay functionality enhanced with pause and summation control.
Function L: Asymmetrical flashing relay (starting pulse off)
Description: Asymmetrical flashing output, starting with the OFF state.
Function Lt: Asymmetrical flashing relay (starting pulse off) & with pause / summation control
Description: Asymmetrical flashing with pause and summation control, starting with the OFF state.
Function Li: Asymmetrical flashing relay (starting pulse on)
Description: Asymmetrical flashing output, starting with the ON state.
Function Lit: Asymmetrical flashing relay (starting pulse on) & with pause / summation control
Description: Asymmetrical flashing with pause and summation control, starting with the ON state.
Function N: Safe-Guard Relay
Description: A safety relay designed for protection applications.
Function O: Delayed Safe-Guard Relay
Description: A safety relay with a delayed activation.
Function P: Pulse Delayed Relay With Fixed Pulse Length
Description: A pulse relay with a delayed output and a fixed pulse duration.
