Description
The TSS Series is a totally solid-state timing module. Its 1A rated, solid-state output provides an excellent method of time control for exposures, dispensing, or for increasing or decreasing a switch closure. Time delays from 0.05 to 600 seconds, in 4 ranges, cover 90% of all OEM applications. Factory calibration of fixed delays is ±5% and the repeat accuracy is ±2%. The TSS Series can be surface mounted with a single screw, or snapped on a 35mm DIN rail using the P1023-20 accessory adaptor. Operation (Single Shot) Voltage must be applied before and during timing. Upon momentary or maintained closure of the initiate switch, the output energizes for a measured interval of time. At the end of the delay, the output de-energizes. Opening or reclosing the initiate switch during timing has no affect on the time delay. The output will energize if the initiate switch is closed when input voltage is applied. Reset: Reset occurs when the time delay is complete and the initiate switch opens. Loss of input voltage resets the time delay and output. Features & Benefits FEATURES BENEFITS Analog circuitry Repeat accuracy + / - 2%, Factory calibration + / - 5% Compact, low cost design Allows flexiblility for OEM applications T otally solid state and encapsulated No moving parts to arc and wear out over time and encapsulated to protect against shock, vibration, and humidity Surface or DIN rail mounting Provides flexibility for installation Accessories P1004-95, P1004-95-X Versa-Pot Panel mountable, industrial potentiometer recommended for remote time delay adjustment. P1023-6 Mounting bracket The 90° orientation of mounting slots makes installation/removal of modules quick and easy. P0700-7 Versa-Knob Designed for 0.25 in (6.35 mm) shaft of Versa-Pot.
