PSIM-AC PSIM-DC PSIM-5V Introduction The Power Supply Interface Module (PSIM) is part of the Orbit Measurement System. The PSIM provides local power to the network when required. Example uses: • Power via the communications cable is not sufficient due to cable voltage drop s.
This equipment is designed as safety Class 1 apparatus to comply with EN61010-1. Service Safety This equipment has been designed and tested to meet the requirements of the Low V oltage Directive (1997) and has been supplied in a safe condition.
W ARNING: Danger arising from loss of ground. During a fault condition and upon loss of protective ground (earth), all accessible conducting part s - including controls that might appear to be insulated - can render an electric shock. W ARNING: Grounding the equipment.

4.0: PSIM Schematic and Pin-out The 5V power supply line from the network is isolated at the PSIM. All modules before the PSIM are powered from the network. Example: Orbit Network Card. All modules after the PSIM are powered from the external power supply connected via the PSIM.
4.0: PSIM Schematic and Pin-out (continued) The PSIM will only supply power to the Orbit Modules that follow the PSIM. Some typical configurations are shown. For more information about PSIM and Orbit Network connection, refer to the Applications section.
5.1 Power Supply The mounting plate must not be removed. The mounting plate is isolated and does not need to be at earth potential. The power supply may be mounted in any orientation. The power supply must not be exposed to fluids or excessive dust. Power supply cooling is by convection; allow room for air to flow around the unit.

Orbit Network Power Supply Requirement s All Orbit Modules are designed to work from a supply voltage of 4.75V to 5.25 Vdc. When power is applied to a module its current consumption will cause a slight voltage drop across cables. Care must be t aken to ensure that all modules have the right working voltage applied.
7.0: Applications (continued) V oltage Drop Estimation The following information is for guidance only when planning an installation. V oltage measurements must still be made to ensure the right working voltage for each Orbit Module. 6 9 51 Power Supply OUTPUT PSIM-AC PSIM-DC PSIM-5V PSIM-AC PSIM-DC see note 1 volt drop (from no load output) V = 5.
PSIM-AC PSIM-DC PSIM-5V 7.0: Applications (continued) Application 1: Basic Small Network Connection. • Power supplied to network from PC via network card, no PSIM used. • Modules connected using standard communication cables. V olt drop total in mV = cable 1 + module (3 off) + cable 2 + module (3 of f) = (15.
PSIM-AC PSIM-DC PSIM-5V 7.0: Applications (continued) Application 2: Large network with modules close to computer and at a dist ance. • Power supplied from PC and PSIM (located at a distance from PC). • Communications via standard communications cable and custom cable.
PSIM-AC PSIM-DC PSIM-5V 7.0: Applications (continued) V olt drop V 1 is calculated in a similar way to the previous example except there is only a single cable and 3 Orbit modules. The PSIM supplies power to remaining modules and are calculated sep arately .
PSIM-AC PSIM-DC PSIM-5V 7.0: Applications (continued) Application 3: Large Network using PSIM-5V and RS232IM for network control. LDN-PS 22 M-3340/1206.
PSIM-AC PSIM-DC PSIM-5V The PSIM-5V is powering the whole Orbit Network. PSIM-5V volt drop is calculated using 12 as the total number of Orbit modules; the RS232IM is included in this number . T otal V oltage drop = PSIM-5V + modules (6 off) + Cable 1 + Modules (6 of f) = (2 x 12 x [3+1]) + 0.
PSIM-AC PSIM-DC PSIM-5V 7.0: Applications (continued) Application 4: Modules located a long dist ance from computer . • Also for a computer that is not suitable for supplying power to Orbit Modules. • Power supplied from PSIM to modules. • Connection via long cable providing RS485, 0V reference and screening.
7.0: Applications (continued) PSIM-AC PSIM-DC PSIM-5V Application 5: Use with RS232 Interface Module (RS232IM). • Communication is via a RS232IM. • Power to the RS232IM and Orbit Modules is via PSIM.
