ANALOG POSITIONER EP 100
The analog Positioner EP 100 with analog input 4 ... 20 mA is designed to operate pneumatic valve actuators. It offers an easy adjustment by means of switches and potentiometers. The modularstructure of this positioner series enables conversion from an analogto a „digital“ or „intelligent“ positioner by exchanging the electronics.
TECHNICAL FEATURES• Configuration by means of switches and potentiometers• Load 300 Ohm• Low air consumption• Stroke 8 to 120 mm (0.3 to 4.7 inch)• Angle range up to 95 °• Supply air pressure up to 6 bar (90 psig)• Single or double acting• Mechanical travel indicator• Reverse polarity protection• Attachment to stroke actuators directly or according to
IEC 534 part 6 (NAMUR)• Attachement to rotary actuators according to VDI/VDE 3845• Protection class IP 65 and NEMA 4X
4.3 EP 100
EXPLOSION PROTECTION:• EEx ia IIC according to CENELEC or „Inrinsic safety“ according
to FM and CSA• Integrated inductive limit switches, independent of device
electronics
ACCESSORIES e.g.:• Gauge attachement for supply air and outputs• Booster relay
