The PAX1 is a flexible low voltage DC powered linear actuator featuring a 25 mm maximum thrust rod stroke moving at speeds up to 60 mm/min and a maximum thrust of 2,890 N all in a flameproof enclosure. The unit is inherently locked in last place as the thrust rod maintains its potions upon loss of signal or electrical power.
The PAX1 can be actuated open loop using two optically isolated switch closure inputs (Up and Down) to move the actuator's thrust rod. The actuator will continue to move the thrust rod in response to the inputs until either of the adjustable stroke limits are reached.
The PAX1 also has an isolated 4-20 mA analog input to proportionally position the thrust rod anywhere within its 25 mm stroke. There is also a 1-5 VDC non-isolated analog input as well. In analog control mode, the unit is fail freeze upon loss of either analog signals.
The actuator also features UP and DOWN push buttons under the cover to facilitate commissioning and to permit local control of the actuator. There is also an 8 mm (5/16") female hex motor drive interface under the cover to allow manual actuator movement.
The actuator also includes two fully adjustable SPDT alarm relays (one High and one Low) providing alarm function when the actuator's thrust rod reaches critical positions within its stroke. The relays are magnetically latched so the alarm switch states are maintained when the power is disconnected. This allows accurate alarm function on systems that remove power from the actuator between adjustments to conserve power as is typically done in solar powered installations.
The PAX1 also offers an optional isolated 4-20 mA feedback output. This feedback feature is functional for both the pulse control and analog control configurations. The unit must be powered to facilitate the feedback output function.
