Timers, phase-sequence and voltage monitoring relays, DIN-rail SMPS.
Trinity Touch industrial controllers are the small DIN-rail devices that time, sequence and protect motor and machine circuits: timers for star-delta starts, delays and cyclic operation, phase monitors that trip a contactor on phase loss or reversal, and voltage monitors that guard three-phase loads. The switch-mode power supplies convert panel AC to regulated 24 V DC for PLCs, sensors and relay modules. All are made in India.
Analog timers come in 17.5 mm and 22.5 mm DIN widths as single-function (on delay, off delay, star-delta) and multi-function units with selectable ranges. Digital timers with a single display give precise settings for process steps. The PSR/PFR relay covers phase sequence and phase failure, and the three-phase voltage monitoring relay adds under- and over-voltage with adjustable thresholds. SMPS units deliver 24 V DC at various current ratings in DIN-rail housings.
Indian buyers select timers by function, time range and supply voltage, monitoring relays by nominal line voltage and trip settings, and power supplies by output current with margin for inrush. State the control voltage available in the panel (24 V DC, 110 V AC or 230 V AC) and the contact arrangement the control circuit needs.

The series asked for most. Any other Trinity Touch part number is quoted the same way.
It checks that the three phases arrive in the right order and are all present. If a phase drops or the sequence reverses, the relay opens its contact so the contactor drops out and the motor is not run single-phased or in reverse.
Add the steady-state current of every 24 V load (PLC, I/O, sensors, relay coils, HMI), then allow 20 to 30 percent margin plus any inrush from valves or lamps. Pick the next standard SMPS rating above that figure.
Electrically the functions match, but the housing width differs, so the panel layout and DIN-rail space decide. 17.5 mm units save space in dense control sections; 22.5 mm units have larger dials and are easier to set on site.
